Find LCM of 756,846,760,786,393 with Prime Factorization
| 2 | 756, 846, 760, 786, 393 |
| 2 | 378, 423, 380, 393, 393 |
| 3 | 189, 423, 190, 393, 393 |
| 3 | 63, 141, 190, 131, 131 |
| 131 | 21, 47, 190, 131, 131 |
| 21, 47, 190, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 131 x 21 x 47 x 190 x 1 x 1 = 884391480
Therefore, the lowest common multiple of 756,846,760,786,393 is 884391480.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
756 x 846 x 760 x 786 x 393 = 150148447908480
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
786 : 1, 2, 3, 6, 131, 262, 393, 786
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,846,760,786,393, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
846:2x 3x 3x 47
760:2x 2x 2x 5x 19
786:2x 3x 131
393:3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 3x 3x 131 = 169776
Therefore, the value for common factors is 169776.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 150148447908480/(1x169776)
LCM = 150148447908480/169776
LCM = 884391480
Thus, we can understand that the LCM of 756,846,760,786,393 is 884391480.
